Who do you think would be the first to fall and the last to fall if to say the void would invade?

Please if you are to post here, please give valid reasons such as abilities of the champions helping to defend and the statistics of the land where they come from like demacia's army or piltover's police force and bilgewater could make a makeshift navy i suppose? also i will try setting up a poll. I would like to say the last to fall if they do would be the shadow isles thresh/yorick/mordekaiser to control all the dead and hecarim to rush through killing multiple enemies then there is vilemaw and elise with their army of spiders karthus with his crowd control walls and his ult to damage all enemies. evelynn to would be a formidable opponent in the fight with her being able to be invisible and sneak behind enemy lines then dissapear. (don't know if i should include maokai since he's from shadow isles but left?) there is kalista but not much is known of her abilities. On the side of the void it woul'd be a hard fight for the shadow isles you have kogmaw to slow and shoot at enemies from range kassadin to move very fast across the battlefield to target the stronger or weaker depending on which hold a more tactical advantage. kassadin could fly use void spikes to go and damage/kill enemies and jump in/fly out after killing enemies to avoid potentially fatal blows. there is cho'gath who can fear and knock up his enemies and take alot of hits letting other get the finishing blow. There is malahar with his slowing abilities and too make an area of void energy damaging all poeple in an area and summoning a voidling too passively increasing their ranks. vel'koz would be a much more back line fighter with his long range slows/knockups and his ult to damage multiple enemies in a line. in the end after comparing these two i think the shadow isles would come out on top with their ability to reanimate the dead and mordekaiser being able to reanimate one of the void champions would seriously help in the fight since it gets buffed based on mordekaiser on power. Now i am a little biased towards shadow isles that's why i think they would do best so if you think some other nation please post i would like to see other poeple's reasoning. :D
